Green Sparklers vs Normal Sparklers

The word "green" in front of a sparkler refers to the formulation, not a separate product line sitting next to the "normal" one. Green-certified sparklers use CSIR-NEERI-developed compositions designed to cut particulate and gas emissions versus a conventional, uncertified mix, while still producing the same spark shower, colour and burn time a buyer expects. Since the Supreme Court's 2018 order permitting green-crackers manufacture and sale, this reformulated version is what's actually stocked as standard, across every size from 7cm to 15cm here. So there's no genuinely "normal" (non-green) sparkler sitting alongside it on this catalogue to compare against. The meaningful comparison for a buyer isn't formulation, it's size.

Size changes two things: burn duration and spark height. The 7cm size is built for small hands and a quick burst, 20 to 30 seconds, which suits the youngest kids in a group who lose interest fast or need the shortest possible hold time. Step up to 10cm and you get the standard entry burn, 30 to 40 seconds, which is what most family packs default to. The 12cm and 15cm sizes extend that further, trading nothing in safety rating for a taller plume and a longer show, useful when you want the sparkler moment to last through a group photo rather than finishing before everyone's ready.

None of the four sizes change the noise profile, the day and night usability, or the apartment-safe rating. They're all low-noise, all usable in daylight or after dark, and all fine on a terrace or balcony. So once you've settled on "sparklers, not something louder," the only variable left is how long you want the burn to last and how tall a plume the group wants to watch.
